- Abstract
Objective: This study aims to evaluate the tensile bond strength of a silicone-based soft denture liner material on denture bases produced via conventional, subtractive, and additive manufacturing techniques and examine the effect of aluminum oxide particle abrasion on tensile bond strength. Materials and Methods: A total of 48 cylindrical denture base resin samples were manufactured using three different techniques: conventional, subtractive, and additive manufacturing. The samples were divided into two groups: control and aluminum oxide particle abrasion. All samples were separated at the center, and the soft liner was applied to the corresponding surfaces. The specimens then underwent tensile bond strength testing. Data were analyzed using Two-way ANOVA and Bonferroni post hoc tests. Failure-type analyses have been conducted. Results: Two-way ANOVA results indicated a significant difference among the denture base resins, while no significant difference was found between the control and aluminum oxide particle abrasion groups. The highest tensile bond strength was observed in the subtractive-manufactured aluminum oxide particle abrasion group, while the lowest tensile bond strength was in the additive-manufactured aluminum oxide particle abrasion group. Significant differences were found between the subtractive and additive-manufactured groups (p=0.022). Conclusion: This study demonstrates that tensile bond strength varies with the denture bases manufacturing technique. While aluminum oxide particle abrasion increased tensile bond strength in subtractive manufacturing, it had no statistically significant effect. Further research should explore different soft-lining materials and consider in vivo conditions for more comprehensive insights.
